9exposure burdens for toxic air contaminants and criteria pollutants, including “ultrafine particles”
10as defined by the Environmental Protection Agency; (ii) identify the likely air pollution hotspots
11and corridors due to high concentrations of traffic-related air pollution throughout the
12commonwealth that should be equipped with new or expanded air monitors; and (iii) establish
